Unlike most free duet arrangements for violin and cello, (which often contain errors or give one part all the melody), Duo.Hansen’s beginner and intermediate duets are carefully arranged by a professional violin and cello team, so that each part is expertly arranged to feel natural in the hand, and kept safely within the difficulty level specified. This way both players feel musical, challenged, and rewarded. Each piece is crafted to support balanced learning and enjoyable ensemble playing.

Every product is marked with a colored wax seal on the cover. Amber = Beginner (Seal of First Light) and Green = Intermediate (Seal of Harmonic Growth).

• Beginner Seal: First position only, simple rhythms, friendly bowings.

• Intermediate Seal: Shifting, double stops, and progressive bowings.
  Each Seal also has 3 sub-tiers (early, mid, late) so you can find your best fit. Product descriptions give detailed guidance.

The Scorekeeper’s Seal System is a collectible achievement path, like musical karate belts but with whimsical scrolls and magic. Students can earn certificates for each tier of Beginner and Intermediate levels by practicing, progressing, and completing challenges. It helps learners stay motivated with a sense of adventure and accomplishment.

Available for music theory: Theory Quest™ and string student practice progress chart: Scorekeeper’s Milestone Maps.

Practice Quest™ is a free, gamified practice system delivered straight to your inbox. Every week for 12 weeks, you receive a scroll filled with challenges, inspiration, and lore. Quests are free to join — you’ll just need your chosen Duo.Hansen sheet music and practice tools to complete the journey. It’s perfect for students who need motivation, structure, or a fun twist on practice.

Lessons with Duo.Hansen are always personalized. We build on strong classical traditions passed down to us, while blending in research-backed approaches. Both of us (Adam and Julia) focus on carefully developing the techniques that let each student discover their own unique voice and interpretation on their instrument. Mastering the basics, learning note reading, developing strong practice methods, and exploring the students expressive power are all heavily emphasized so each student can reach their full potential.

Theory Quest™ is a magical learning journey that turns music theory into an adventure. Designed especially for young students who enjoy whimsical tales, it introduces note reading and music theory concepts through story-driven lessons and playful activities. Along the way, students meet helpful guides and face mischievous villains, making every page feel like part of an unfolding quest.

*Science shows that practicing note reading away from your instrument can actually improve sight-reading fluency. By separating reading skills from playing, students strengthen their ability to recognize patterns quickly, and later apply them with more confidence at their instrument.

Each Theory Quest™ activity is re-printable for extra practice, making it easy to revisit challenges as skills grow. While the materials can be enjoyed independently, they are most effective when paired with teacher guidance. The result is a blend of fun, story, and skill-building that helps students gain fluency while keeping the joy of discovery alive.

*The principle of reduced cognitive load (from Cognitive Load Theory, Sweller, 1988)

Science shows that practicing reading skills separately from playing reduces cognitive load – meaning the brain can focus on one task at a time. This builds fluency and recognition of musical patterns more quickly, without the added pressure of playing technique. Later, when students apply these patterns on their instrument, they do so with more confidence and ease. At Duo.Hansen, this “reduced cognitive load learning” is one of our core teaching approaches, blending artistry with science-backed methods.
